Numbat is a statically typed programming language for scientific computations with first class support for physical dimensions and units.
It is a continuation of insect.
This is free and open source software.
Key Features
- Physical dimensions as types – static type system where physical dimensions like Length and Time act as types.
- First-class physical units – focused on computations with units. Units are therefore treated as first-class citizens.
- Comprehensive standard library – comes with a large number of physical dimensions and units (SI, US Customary, Imperial, Nautical, Astronomical, Atomic, Nuclear, …).
- Strict syntax – parser never tries to be “smart” on syntactically incorrect input. This means you will either get a (descriptive) error message, or you can trust the result of your calculation.
- Excellent error messages – aims to provide descriptive and helpful error messages.
- Interactive terminal – interactive use-case with small “one off” computations.
- Modular and customizable
- Assertions – provides an assert_eq procedure that allows you to check for exact equality
